Know all 'num by these presents I That "I, famme BALL, of the city and county of Worcestenand Commonwealth of Massachusetts, have invented' certainnew and useful Improvements -in Branches for Wrought-Iron Cement-Lit ed Water- Pipes; and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanying drawings, forming a .part of this specification, in which- Figure 1 represents' a perspective view of my improved branch;

Figure 2 represents a transverse section of the same, through the central part; and

Figure 3 represents a longitudinal central section of my improved branch without the cement lining.

To enable those skilledn the ait towhich my invention belongs, to make and use the same, I will proceed to describe it more'in detail.

The nature of my invention consists in forming the blanches of cement-lined water-pipes of wrought-iron, inthe peculiar-,manner hereafter explained.

In the drawings, the part marked A is the main pipe,l and B, the distributing-pipe, which is joined to the main pipe A, as follows:

A wrought-iron plate', C, is out to the required size, heated,and placed'u'pon aconcavd cylindricalmould, corresponding to the size of the main pipe A. The mould'. has, at its central part, a circular opening, .which corresponds to the size of the distributing-pipe B; Apt the intersection of the two cylindrical surfaces, the mould is rounded to prevent damaging the plate when struck by the die.

The die conforms to the shape of the mould, and is composed of two parts, the face of one being a half cylinder, having i`n its centre an opening, through which works the circular part that fits the opening in the centre of the mould. .It is so arranged that the half cylinder strikes the plate C first, and forces it into the mould, giving it the cylindrical form to fit the surface of the main pipe A, and holding itin position, -while the circular-part of the die immediately follows, and, either by steady pressure or by successive blows, as maybe preferred, forces out the central part of the plate C into the circular opening in the mould, thereby forming a protuberance, D, somewhat resembling the bottom of a tin dish, as indicated in section by red lines, fig. 3 ofthe drawings.

The plate is then taken from the mould, and the cir- "scribed, and for the purposes stated.

cular portion D is punched out, leaving an opening, the size of the distributing-pipe B, the end of which is inserted in the opening, and slightly swelled at the edge, by hammering, when holes are punched through both, and rivets, a, inserted to secure them together.A

' A hole, somewhat larger than the end of thedistribnting-pipe, is tl1en cu't in the main pipe A, and the plate C and pipe B being plaed over it, the edges of the -plate O are secured to the pipe A, by rivets f. The whole Visthen lined with cement, E, as indicated in the drawings, thus forming a branchof the same substance and quality as the other portions of the p1 or it may be in a piece of suicient size to be riveted entirely around the main pipe A. I prefer, however,

to make the branch as shown in the drawings.

It will be s een, by the foregoing description, tha the branches thus formed are as strong and durable as the other portions of the pipe, -and are not liable to break, or'crack, like joints formedby soldering, which is the ordinary and most common mode of forming the branches for wrought-iron cementlined water-pipes.

.lheyvare ea'sily and lcheaply constructed, and are superior' to any branches in common use for the purpose, and obviate one if not4 the greatest objection to the general use of wroughtiron cement-lined waterpipes. 1

Having described my improved branch for wroughtiron cement-lined water-pipe,

What I claim therein as new and of my invention,

and desire to secure by Letters Patent, is-

1. A branch and offset, D, for facilitating the attachment of branch-pipes, when said oifset is formed from a'solid plate of metal, substantially as shown and de' 2..' The combination,'with the pipes A and B, of a plate, or cap, C, provided with an offset, or projection, D, substantially as and for the purposes s et forth.

3. A branch for wrought-iron cement-linedwaterpipes, the part` of 'which are constructed in themanner and form s bstantially as shown and described.
